| Popis: | The paper presents a study of the effect of a constant magnetic field (CMF) on the basic processes of quercetin electrochemical reactions. According to the observation made in previous studies, the presence of a double bond in the C‐ring of quercetin enhances the antioxidant properties of that compound, whereas the presence of −OH groups also affects the antioxidant properties. Using cyclic voltammetry it was found that the constant magnetic field improves the efficiency of quercetin electrooxidation, especially of the third stage of the process, i. e. the stage in which the oxidation of the OH groups in the A‐ring is the most difficult. The use of HPLC confirmed the electrochemical measurements and the results of cyclic voltammetry studies. The beneficial effect of the magnetic field on the efficiency of quercetin oxidation was confirmed by the results of impedance spectroscopy measurements. The effect of a constant magnetic field on the processes of quercetin electrochemical reactions has been investigated. Using cyclic voltammetry and impedance spectroscopy, it was found that a constant magnetic field improves the reaction efficiency at the stage in which the oxidation of the OH groups in the A‐ring is the most difficult. For comparison, a study of the effect of magnetic fields on the basic processes of alloys electrodeposition and on the Kabachnik‐Fields reaction is reported. |
